CLARE AUBREY IIUSTON, OE PHILADELPHIA, PENNSYLVANIA, ASSIGN'OR TO IIUSTON, ASHMEAD & 00., LIMITED, 013 SAME PLACE.

GAGEFOR PLATE-PRINTING PRESSES.

SPECIFICATION forming part of Letters Patent No. 494,955, dated April 4, 1893. Application filed September 15,1892. Serial No. 446,026. (No model.)

To on whom it may concern.-

Be it known that I, CLARE AUBREY Hus- TON, a citizen of the United States, residing in the city and county of Philadelphia, State 5 of Pennsylvania, have invented a new and useful Improvement in Gages for Plate-Printing Presses, which improvement is fully set forth in the following specification and accompanying drawings. My invention consists of a gage or guide attachment to a plate printing press for effecting the registry of the paper or other material, and causing uniform work to be produced,

the construction of said guide being hereinr after fully set forth.

It also consists of the novel construction of the gage, whereby the paper or other material to be printed, is prevented from entering between the same and the support thereof.

:0 Figure 1 represents a top or plan view of a gage for a plate printing press embodying my invention. Fig. 2 represents a side elevation thereof. Fig. 3 represents a transverse section on line 93, m, Fig. 2. Fig. 4-. represents a transverse section on line y, 3 Fig. 2.

Fig. 5 represents'a perspective view of a device as applied to the press. Fig. (i represents a perspective view of a detached portion. Fig. 7 represents a transverse vertical section of a portion on line a, s, Fig. 5, on an enlarged scale. Fig. 8 represents a perspective view of another form of the gage.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings; A designates the bed plate of a plate printing press, as well known.

B designates an angular plate which is secured to the side of said bed plate A by means of screws 0, or other suitable means which pass through openings in the limb D of said plate B.

In the horizontal limb of the plate B are transversely extending slots E, through which pass the screws F, the upper ends of which are connected with a T-shape or shouldered bar G, it being noticed that said bar may be moved laterally so as to be set nearer to or farther from the side of the bed plate A, for 5Q purposes of adjusting said bar in transverse direction to the work to be accomplished on the bed plate A.

H designates a sliding gage which consists of a body with depending sides, the same freely embracing the bar G, and having in one of its sides J, the set screws K, which are adapted to tighten against the head of the bar G, said gage being movable in the longitudinal direction of the press, so as to be adjusted in said direction relatively to the work to be accomplished on the bed plate A.

In order to prevent the passage of paper or other material between the gage and top of the bar G, an arm L is hinged to the body thereof, and a spring M is provided, the same bearing against said arm in such manner that a downward pressure is exerted on the latter, so that it bears snugly and closely against the top of the plate l3,without however preventing the adjusting movements of the gage.

In Fig. 8, the bar N is adjustable in transverse direction by means of the slots P and screws Q, similar to that of the adjustment of the bar G, and the angular plate R which supports said bar N has longitudinally extending slots S to receive the screw T, which passes through a slot in the gage U, and is provided with a thumb nut V, whereby said gage is adjustable in the longitudinal direction of the bed plate, similar to the gage H.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. An angular plate having openings in its depending limb, and transverse slots in its horizontal limb, a bar on said plate, screws passing through said slots and having their ends in said bar, a gage embracing said bar and movable thereon, a spring controlled arm pivoted to said gage and means substantially 0 as described for securing said gage in position, said parts being combined substantially as described.

2. An angular plate adapted to be secured by itsdepending limb to the bed plate of a printing press, and having transverse slots in its horizontal limb, a bar adjustable on said plate by means of screws in said slots, a gage embracing and movable on said bar, an arm pivoted to said gage, and a spring secured to I00 said gage and bearing against said arm, said and bearing against said plate, saidparts bepartsbeing combined substantially as deing combined substantially as described.
